METHOD, DEVICE AND PROGRAM FOR EVALUATING HEALTH STATUS AND/OR GROWTH STATUS OF LIVESTOCK

Provided is the information processing method and the like, which can provide a person involved in an animal (for example, a livestock animal such as a pig) with sufficiently reliable information so that the person (for example, a farmer and an animal doctor when the animal is a livestock animal) can conveniently and objectively grasp any one or both of a health state and a growth state of the animal thereby contributing to realization of a rational rearing environment of the animal. In the present embodiment, at least one item of growth potential, nutrition state of a protein, utilization efficiency of an amino acid, glucose metabolism, stress, appetite, feed efficiency, growth speed, and growth prediction is evaluated by using a blood concentration value of at least one amino acid of Asn, Ser, Gly, His, Thr, Arg, Pro, Tyr, Val, Met, Orn, Lys, Ile, Leu, Phe, Trp, and 3Met-His, obtained from an animal, or a value of one or a plurality of formulae that include an explanatory variable to be substituted with the blood concentration value, calculated using the formula and the blood concentration value.
